From e73d866c6fc7dfad2fb7dd87345c90029bbda59d Mon Sep 17 00:00:00 2001 From: David Bauer Date: Mon, 26 Oct 2020 21:59:47 +0100 Subject: [PATCH] ipq40xx: enable RX hash / CTAG TX offloading for single-phy This re-enables offloading features disabled by commit 9da2b567605b ("ipq40xx: fix ethernet vlan double tagging"). Single-PHY devices use port-based VLANs on the switch, therefore no S-TAG magic is involved here. Re-enabling these features restores throughput back to 950 Mbit/s.
